The hidden cost of subcontractor maintenance

What follows is a composite, assembled from conversations with O&M and facilities contractors rather than any one customer. The details are typical. None of them are specific.

A contractor runs quarterly inverter services across forty solar sites for six asset owners. In-house crews cover the sites near the depot. Three subcontractor firms cover the rest, and one of those firms passes its northern sites to a fourth outfit the contractor has never met. The work gets done. Evidence comes back as photos in a group chat, a PDF report ten days later, and an invoice. Someone in the office types what they can into the tracking spreadsheet.

The subcontractors’ day rate is on the invoice. Everything below is not.

Re-keying

Each PDF is read by a person and transcribed into the spreadsheet: date, site, what was checked, readings if the report has them. At forty sites and four services a year that is a hundred and sixty reports, each taking somewhere between ten minutes and an hour depending on how the subcontractor writes them up. Quarter-end owner reports are then assembled from the spreadsheet, by hand, per owner, over three to five days. That is skilled time spent converting one document format into another.

A disputed SLA

An owner’s asset manager disputes a response-time SLA on a tripped inverter. The contract says four hours to site. The contractor believes the subcontractor was there in three. The proof is a photo in a WhatsApp thread, on a phone belonging to a technician who works for a firm the contractor does not employ, with a timestamp that shows when the photo was sent rather than when it was taken. The credit note gets issued. It is cheaper than the argument.

One of those a quarter, across six owners, is a margin line. It does not appear in any budget because it does not have a name.

The person you cannot identify

The fourth-tier outfit sent someone to the northern sites. The contractor does not know who. If the owner asks whether the person who signed off the switchgear thermography was qualified to do it, and whether their certification was current on that date, the honest answer is a phone call to a phone call. Under most O&M contracts the contractor carries that liability regardless of how many tiers down the work went.

Rework that does not show up anywhere

Some subcontractors are better than others. Everyone knows which ones, informally. It cannot be shown, because first-time-fix and rework rates per provider per asset class are not recorded; the return visit is just another work order. When the contracts come up for renewal there is no basis for paying the good firm more and the poor one less, so both get the same rate and the poor one keeps the northern sites.

A warranty claim that never gets made

An inverter fails twice in eighteen months. Each failure was handled by a different subcontractor, reported in a different PDF, keyed into the spreadsheet under a different description. The pattern is invisible. The OEM warranty would have covered the second failure. The claim window closes.

Why it keeps happening

None of this is carelessness. It is the predictable result of maintenance software that is licensed per named user and designed for employees. A subcontractor who does three jobs a year for you is not going to be issued a seat, install an app, sit through onboarding and remember a password. So they are not in the system, so the record of their work is not in the system, so the system holds a partial account of the portfolio and the rest lives in chat threads.

The arithmetic makes the point. Two hundred subcontractors at forty dollars a seat a month is ninety-six thousand dollars a year for people who each touch the system a handful of times. That is a cheque no contractor signs. The pricing model creates the data gap, and the data gap creates every cost above.

What would have to change

The subcontractor has to be able to do the work inside the record without being a licensed user of it. Concretely: they receive a link, open it on whatever phone they have, see the checklist, take the photos, enter the readings, sign, and close. No account. Their photos land against the asset with a capture timestamp. Their identity, and the identity of anyone they passed the job to, is recorded in a chain the contractor can see. Their certification is checked before the job can be accepted, not after the audit.

With that in place the re-keying disappears, the dispute has a timestamp, the person is named, the rework rate is a number, and the second inverter failure shows up against the first.

Where Facterra sits

This is the problem Facterra is built around: work orders completed from a link by people who do not work for you, with structured evidence returned against the asset, on an asset model that has run in fifty-odd industrial facilities since 2017. We are new to renewables and critical facilities. We are not new to the record.
